We bolted the 40-inch Trail Grapplers onto a set of Mickey Thompson Classic Lock black wheels with Inner Air beadlocks. We really like the look of these wheels, but the outer faux-beadlock ring (which we had sandblasted the black paint off of) took serious abuse during the Ultimate Adventure. The Inner Air beadlocks are difficult to install, and we actually had some issues with two rims slowly leaking around one of the Inner Air valve stems, but they worked well at locking the bead in place at low tire pressures.
